水稻不同栽培模式叶龄跟踪调查分析

运用叶龄诊断技术,研究水稻不同栽培模式的植株生长发育进程和产量性状。结果表明,叶龄进程前期与秧苗素质呈正相关,后期与气象条件呈正相关,而与栽培模式关系不大。而栽培模式与分蘖进程、成穗质量、产量性状关系极大。在本试验区内,几种栽培模式各具特点,但钵育摆栽秧苗素质好,水稻产量最高,比常规栽培提高12.6%。

Investigation and analysis about different cultivated mode on rice

Use the. technology of diagnosis leaf age to research the plant's growing development and yield's character of .rice at the different cultivatable mode. The result indicate that the early leaf age course had the positive correlation with the seedling's inner quality, the later period had the positive correlation with the weather conditions and had the less correlation with the cultivatable mode. But cultivatable mode had the huge correlation with the tillering process, the quality of fringe and the yield's character. In the experimental area, the different cultivatable mode had its respective characteristic, but cultivation use bowl had the merit that stuff of seedling is well, the yield is high and it increase 12,6% than groovy cultivation.
